Happy to know my 12 hour gaming addiction isn’t harmful...yet
Only 12 hours up ur game u got 20 hours in the day for gaming true gamers can exist off only 4 hours of sleep a night and you should falling asleep to a 4 hour compilation of speed runs
I got my 23 hours of gaming and my 1 of eating well make that sleeping and eating lol I can sleep eat.
@@nipslapper Pretty much me, except I fall asleep to anime because the weeb in me is trying to claw back some time.
@@dogavolo2404 a true shame I cannot achieve such incredible feats I can survive off 1 hour of sleep but to do so I must snort a quarter tub of g fuel every day

Yeah I've had it for so long that it just seems natural now. I think it reduces the effects by some amount?

Mine is like that cause it just flat out hurts my eyes less.

I'm such a big fan of dark mode on all my apps. Definitely a big difference when using my phone a lot.
@Regular dude on internet. a lil late too but I use dark mode on most of my apps and it's pretty enjoyable for me especially at nighttime
@@sansnitizer *Also* late, but I also think dark mode is very nice. It doesn't put much stress on my eyes. As light mode.....
maybe im late too but it's debatable if dark mode is better cause it forces the pupils in the eyes to contract(? i think, bad english, sorry) cause that's our night vision in the eyes, dark mode is great when used accordingly and i love it
I have dark mode on RUclips
I wish in the future someone could invent something that allows humans to stare at the screen for so long without causing any eyestrain, dried eyes, headaches, and fatigue. And allows humans to use screen time for so long let's say about 10 hours and still didn't even experience any blindness or eyes to hurt, not even causing blurred vision...

Blue light is bad for your eyes..... films this video with a blue background lol 😂
Wrong kind of blue light. The blue background is a very different thing from the screen glow. The actual color doesn't have much to do with it.
blue light & blue color are totally different things ... staring at any color is perfectly normal but blue light coming off from screens are a bit worrysome for eyes !
Its like you didnt watch till the end
Maura McDonnell seems like someone commented without finishing the video
I was going to make the same satirical comment. Also, pretty sure that it is still funny to me despite watching the entire video.
its not the blue light that kills you, its the habit of sitting at one place and chilling all day that kills you
lmao tru
Why can't parents and the media think of it like that

@Laika Baros no, sitting all day is unhealthy, you definitely want to balance the screentime by exercising for exampls
@@cnisp7198 bruh this is literally me Im just always in my room since the quarantine whenever I go out I can see my eyesight getting worse I might have to get it checked up coz even if it's not too far it's already blurred 😭
I have a suspicion that it's about focal length, not about the light from the screen. We are focusing on things that are a lot closer to us for a lot longer than humans used to have to. It may be contributing to nearsightedness.
I was thinking along those lines too when I clicked. I wish they would've talked about that hypothesis
I am reasonably sure, that there was a video on that about one and a half years ago.
It does not. There was a study done on kids in elementary school. One group from Australia (lots of studying and reading of things close by) and another group from somewhere in central Asia (much less time spend indoors studying or reading). Which compared the rates of nearsightedness and found no correlation.
I played games and was on the computer a lot as a kid, now I wear contacts for nearsightedness. Might be correlation or not
@@Trekki200 From memory, I believe that video mentioned that the group that got more sunlight was less likely to be nearsighted but the issue was confirming that theory was/is hard to do since time outside was self reported.
We have being reading books, papyrs and pergamens since more than few years...
I have a feature on my laptop called "Night Light" which changes the light from blue light to warmer, yellowish colors. Does this counter the effects of blue light screens?
Yeah
i wondered about this too, even youtube has a similar feature but i doubt its effective lol
A bit. The blue from your screen typically only emits at one or a few specific wavelengths, and devices with "night light" just reduce the amount of blue in the mix rather than shifting the wavelength.
I have this feature but I never use it because it annoys the hell out of me. But it might be better I think. I sometimes feel my neurons die faster when watching my screens.
@@oanaalexia you cant feel neurons die wtf

I think the worst damage of screen light is because it develops sleep disorders. Because of it a lot of other problems come together as well.

'Why do I always have headaches? It's so unfair!' I say, while staring at my screen with bloodshot eyes, mindlessly scrolling for 4 hours straight, sleep deprived, and dehydrated
how are you now
I've used computers for months for large portions of a day with no issue. I once played a game on 3x3 screen on that computer for a week and my eyes became bloodshot so I took a break and quickly recovered. It's not necessarily how long you play, but how hard you focus on a small space that can hurt your eyes. Always use full screen.

~ flips tables ~ there is a huge difference between energy density and energy amount.
Smaller wave lengths have features like more flips of polarization in a given spacial region, and they effect atoms/have deeper penetration.
It is like saying a a pound of lead has more energy falling than a pound of feathers because we see the lead do more damage. A pound a force at x speed is that force, regardless of it's size.
100 watts of red and a 100 watts of blue are the same power with vastly different reactions and spacial flux densities.

It definitely can hurt you if it’s 1 in the morning and you get a phone notification . You check it... you have been blinded by the brightness forgetting you had it on max brightness
Why put it on max brightness in the first place-
One observation to be made: damages due to energy deposits in materials are not proportional to energy of incoming photons, in special mode there are threshold effects which may come into play. Below such thresholds even increasing the intensity of the illumination would not permit specific reactions. Said otherwise certain chemical reactions may not be able to take place at energy E but at may at energy E' (where E'>E) and above. It is true that once the minimal (or the proper) photon energy is available, the intensity of light gives proportionality to damages which may occur.
Interesting video. I've heard a lot that screens are damaging to your eyes and I'm glad SciShow made a video on it.

I can already see this being one video in the series about screens that you'll do in the future. Right after this one there will be a video about blue light from screens and how it affects sleep. I KNOW this will happen.
I keep my phone at Night Shift on all the time to where i hate when I turn it off, it burns my eyes if I stare too long at the blue light.

Thank you guys for covering this. I saw some articles being tossed around based on one study saying screens increase macular degeneration. But I couldn't find any comparisons to natural light. If the former study was the final say it would be damning for anyone that works with computers.

Isn't the blue light from screens only at a third of the power required to cause any kind of damage?
I now respect this channel for giving credit where credit is due
>blue light is bad
>background is blue
but knowing sci show, thats probably 470nm blue isnt it
Well, it depends on the LEDs in your screen.
Fair enough, lets hope this phone isnt killing me
Or my computer monitor
Or well
Any of the 59 billion screens i see
Blue light is different from blue background. The light he is talking about is the light that emits from the screen.
Why is it that when I first got into gaming my eyes felt like they were going to die after my 12 hour gaming session, and now I can stare at screens all day and I don’t have any discomfort. Did my eyes get use to screens, or did I just learn to blink?
My guy has been going to the gym!
Nice!!! Looks like he has worked hard! Good job, friend!
I like how you say one blue is less harmful than the other then put color similar to the harmful looking blue as background to the speaker. Bravo!
i always make my background a darker color if i can, it seems to make my eyes feel a lot better. staring at a bright white screen all day kills my eyes.
I'm making a report for my mum about the pros and cons of devices and this was very helpful thank you
Jeez there are so many comments saying how the blue background is ironic. Blue light is NOT the same as the colour blue. Do some research pls
Guess what, blue light hitting your retina is what causes you to see the colour blue you moronic fucktard
EDUCATE YURSELF
@Jun Sen Ngooi What's ironic is you telling people to do research, but what you're saying isn't correct itself. Seeing the color blue DOES mean you're seeing blue light.
@@DANGJOS screens always have blue light. Its not the use of color blue. The color could strengthen the effects but either way its the same thing no matter what color.
@@droson8712 That's not correct. If my screen is on red light only, then every pixel has that filter to remove most of the blue light. It's true that some blue light is still there, but it is *far less* intense than if the screen were blue. So to claim that it's the same, regardless of the screen color, is just false.
That's why I have to wear glasses whereas before I didn't need. Genious. You're such a scientific genious.
0:15 Yes, i am watching this video after we have had an apocalypse.. :'P
One point that's being ignored is the background intensity. It's bright outside, so when you stare at the sky, your pupils constrict to reduce the incoming light. When you're staring at your phone at 2am in a dark room, your pupils let in more light, which is furthermore concentrated at the center of your vision.
I read about something similar a few months ago, but couldn't figure out the frequency distribution of the blue in typical screens. I've heard a few claim that it's not far from the 449nm, but this is a case where details matter.
I know that if I tell my mom about this, she will just start talking about radiation then ask me if I have done my homework and then just go away
What when u use several monitors setup...... this means light etc can shine in to your eyes at a bad angle and damage the eye , right ...? like the light from the side monitors can reflext other light etc directly in to your eye and damage it ....
The second I got reminded about blue light, I instantly turned on my blue light filter, until I found this out 😂
25 years, 4-16 hours of sitting in front of a screen near daily. My eye sight is as good as it was when it was first checked by a doctor back then, beating most people I know. Thus I really don't believe at all that screens can damage anyone's eyes. It's likely something else.
TO ANYONE READING:
Always activate low blue light mode.
To anyone who watched the video: you already know the final conclusion was "it's not a problem" so, you know, or not.
@@BTheBlindRef it still reduces eye fatigue and makes it so that those temporary annoyances he talked about early in the vid are less, you know, annoying
Giona Cantarutti when I started gaming my eyes would hurt after 8 hours, but now that I have gotten use to extended times in front of a bright screen, my eyes feel completely normal. Why?

Okay, so coming from an Optician, you people need to know 4. things. 1: The blue light that we are talking about is (mostly) not in the visible blue light spectrum (The video is kinda misleading/inaccurate to that point.) 2: Yes, most of our exposure to blue light is via the sun, which is why your optician tells you to wear you blue-light blocking lenses all the time, and not just in front of your compy. 3: I personally own lenses with and without the blue light blocking technology. My eyes experience much less strain when I use my blue-blocking lenses. That's really all I need to tell myself and my patients that it's something worth taking seriously. 4: Your eyes are relaxed when you are viewing something far away, but they constrict when you view things up close; ask your far-sighted friends- this means bad headaches after a while. The whole "Take a 20 minute break from your screen" thing will save your life.

@SciShow A correction at 2:31 470 nanometer light will not appear turquoise to most people; it appears pure blue.

Yes we have an apocalypse now but it makes us in front of screens more than before 😢
Yesss
two possible reasons why the test in animals showed damage was probably due to mice being somewhat nocturnal otherwise if the tests they were performing were only using the cells that specifically detect light but not using all of the cells that make up the eye itself, it's possible that the unsheltered ocular cells were more susceptible to damage from light. without the rest of the eye there. It is also plausible that it was some combination of the two factors as well.
My doctor said lights from screens don't damage our eye n here I am checking if that's true 😂
thanks man, but there is still one more question: can your eyes be damaged if you watch something close for a too long time? I have not been very good at the 20 20 20 rule you mentioned here, for eksample playing games for surely mopre than 3 hours at a time, maybe that is why I'm near sighted?

Mom:Its that damn phone!
All three of my kids have terrible eyesight and wear powerful glasses. I worry about the time they spend on screens. Would there be greater danger with the magnification of the strong prescription lenses?
Are there glasses with lenses that can effectively block the 449 nm blue light but keep the rest of the visible light spectrum intact? Or has that not yet been invented?
If I shall be honest, then I think it can be done. I mean there is already some kind of fliters to help with different colour blindness, as they block some light wave. But I guess it is question about time and what we have to make it
That actually already exists, funnily enough some professional gamers use them.
@@SiirEgg Yeah, I knew something like that alread are out
They usually block up to a certain wavelength and everything below it, so if it blocks up to 449 nm, then the glasses will appear yellow.
so are you saying all those who say that looking at mobiles or computer will weaken your eyes are wrong? if thats it, then its good. can someone sum it up for me.? thanks.
Can you talk about the effect on eye sight?
Then why do you have blue background color?
I listened to this video with my eyes closed.
Ive been project manager for lots of companies and they hire cheaper coders from countries like india (they arent bad but work in less amount per hour and also work more than others from NA) and they have shrunken eyes darkest eye circles which put normal dark circles to shame also some worst cases have red eyes like theyve smoked tons of weed... i sheldom meet with them face to face and when i did once i remember this guy saying that he gets enough sleep yet he has eye irritation, eyes being heavy, burning sensation in the skin around eye sockets he looked like he hadnt slept for a week straight... also i face eye irritation if i use electronics for prolonged sessions... so i think screens do affect eyes
Wait... I was literally googling about this 3 days ago. Oh no, SciShow is watching me!

Interesting, but I’m confused is sunlight good for your eyes or bad for your eyes because this video says it can break down eye molecules, but there was another scishow video that said you were less likely to have vision problems if you got lots of sunlight
Don't stare at blue light. Said in front of a blue background.

Probably so the background animation doesn’t get messed up.
I believe screens do have a long term effect on eyesight. Here's why.
I got into the habit years ago when I was a child of using mainly my right eye to watch my phone screen and covering my left at night. Whenever I watched a screen under my covers secretly, I always kept my left eye closed so if I needed to get up, I could still see in the dark as my eye would always be adjusted to the dark.
Today I'm short sighted in both eyes but my right eye is noticeably worse. My vision in my right eye, the one I use to watch screens at night is declining much faster than my left eye.
" Some sort of appocalipse " Covid 19
Blue lights block melatonin production which makes it harder to sleep. Sleep deprivation can cause all kinds of problems. The anxiety I get from school makes it hard to sleep at night which forces me into sleeping in because if I don’t it makes me susceptible to seizures. The 4 causes are stress, sleep deprivation, alcohol, and missing doses.
so by watching this video, I'm damaging my eyes... kowalski analysis🐧
We are screwed.
TakiDDine boufedeche but because you didn’t watch the video, your eyes aren’t damaged, and you’ll never find out that they won’t be damaged either way

LMFAO
Most screens and monitors will allow you to adjust not only the brightness but the color, so you can get something that's not so harsh or glaring to view. But I admit I tend to prefer the bluer screens to the 'warmer' yellowish screens.
SciShow: Blue Light is dangerous.
Also SciShow: *puts up blue background in videos*
so, are u saying phones emit less blue light than sunlight?
Hermit all the way! Science supports it!
(Though i will say that my vision got almost twice as bad when i started using my phone up close so much. I have a blue light filter on my glasses now, and i believe the doctor that was telling me that it's a big part of my problem)
Doctors don't necessarily know what they're talking about, unfortunately. They're not scientists, and they aren't required to read papers or keep up with the current state of knowledge. Lots of doctors believe in outdated medical "knowledge" or techniques.
@@mightyNosewings not true.
It's extremely true, many doctors out there tell patients whacked out myths, incorrect wivestales, or ridiculous pseudoscience from the past century, as do nurses.@@anullhandle
@Justin Chen , Forced? You need to find another Dr. They also have some training in statistics and know how to properly parse a study in context of the body of knowledge and not make wild ass extrapolations from the latest Internet craze. There's also having to pass the boards all over again if they cross state lines. The 40k a seat seminars with a bunch of hours old severed heads to practice the latest techniques, hours reading journals etc. Other small trifles like getting your bs in electrical engineering then medical school then neurosurgery... Not to say if you lined 10 Doctors in a row about half would be below average.
I think that nearsightedness is just humans trying to adapt to constantly looking at something close to you and your eyes evolving to optimize viewing things at close distances.
Blue light can cause eye cells do die:
Mean while has a blue background
This is crazy you made a video about this... I spent the morning getting glass out of my eye ball. While doing so I had a flashlight pointed at my eye trying to find the glass. Well, I noticed if I held it in the same spot, it literally felt like it was burning my eye, especially on the white part, too.
